Support Team replied the topic: How to setup a cron job for XTDir SobiPro
I'm sorry, we've applied the same workaround and test it in our server. The page runs, but it also requires several more fixes to execute successfuly. As the modifications are so extensive, we don't recommend to change the file so heavily.
Since your hosting doesn't allow Joomla Cli Apps, our recommendation to the long term: execute the Index operation "On Page Load" mode.
